What cans are we using on SBRs and AR pistols?

More like what he said, she likely does not agree.

I’d almost wonder if the 5.56 conversion in the SOCOM Rattler is specifically for training/sims and nothing more..

A good point, but I tend to doubt it myself. You can find 5.56 all over the planet. 300, no, it's a niche rnd and you rarely go to war with gun using a niche rnd so the option of either makes very obvious sense to me. I could be wrong and it's as you say.

If anyone gets to go to war with whatever they want, it’s SOCOM (more JSOC but still).

Want vs pragmatic considerations are two different things, hence the options of both. That's my guess and I personally doubt it's simply training related. Your mileage may differ.

I have seen the chrono data from 5" and 7.5" AR PDW, and the numbers, at least from the guns used for the chrono, were essentially the same. Both were above 2400fps for a 55g projectile. That's more than viable in the PDW role, which I have no doubt SOCOM concluded same, and again margin superior to any pistol, PCC, or dedicated PDWs in mouse rnds like 5.7.

Yes, primarily with 11.5” and 14.5” guns, with some 10.3” and 10.4” ones still about.

And now they will be 5" in the PDW role. Who woulda thunked it? SOCOM and me apparently. I kid

Keep in mind, USSOCOM, or a similar umbrella bought MP7s, too. I was issued one (for PSD work), and thought it was gay.

I'd think still better than a pistol or PCC for it's limited intended role, and before short barreled ARs based guns where viable. Not sure if mentioned this in the thread, but back in the day (circa mid/early 90s I think), a buddy of mine was ret SF, had been the armorer for a time, and was then on the SWAT team. Some company, I forget brand, sent him an AR pistol to play with to see what his thoughts were etc. According to him various "nasty boys" as he called them were assessing the viability of such a gun. We went to the range with some others all excited about this crazy short AR.

Long and the short of it was, it was Jam O matic POS. It could hardly get through a mag without issues, regardless of the various loads used, his sitting at the table trying to troubleshoot and diagnose the issues etc, but it didn't work. When it did work, accuracy was terrible also I recall.

He sent it back with obvious opinion that while an interesting idea, not even close to ready for prime time

They are now ready for prime time (unless someone want to claim SOCOM does not know what thy are doing either...), with obvious drawbacks, and development of things like 300blk.
